SCHEMMEL HOOD CONSTRUCTION Application filed April 29, 1982. Serial, No.608,282.

The invention relates to hood constructions and it has particularrelation to the manner of hinging parts of the hood together and to avehicle body.

In certain respects the invention relates to that disclosed in my priorapplications for patents on hood constructions, Serial No. 588,566 filedJanuary 25, 1932, and Serial- No. 602,516 filed April 1, 1932.

Similarly to the application for patent last filed, one object of thepresent invention is to provide a hood construction in which the wingsof the hood are hinged directly together by coacting rolled edges andhinged to the radiator and the cowl of a vehicle without necessitatingthe use of a supporting pivot connecting such parts of the vehicle.

Another object of the invention is to provide a hood construction inwhich the wings of the hood are hinged together and to the radiator andcowl of the vehicle, directly'by rolled edge portions of the wingswithout requiring the use of any separate pintles, pins or the like.

Another object of the invention is to provide a hinge construction for apair of plates or the like, in which a rolled edge portion of one of theplates constituting a part of a rolled edge hinge connecting them, maybe employed directly as a pintle or pivot portion for pivoting theplates on a stationary support.

Another object of the invention is to provide an improved hingeconstruction for hoods, of this general character, which is soconstructed that the outwardly exposed and finished surfaces of the hoodin the region of the hinge will not be marred, scratched or otherwiseinjured during any opening or closing movement of the hood wings, andwhich has a smooth and efiicient manner of operation throughout suchopening and closing movements.

Another object of the invention is to provide an improved hood winghinge, which has desirable flexibility to the end that un desirablestrains will not be imposed upon the pivotal connection between thewings,

hood and vehicle in closing or opening of either wing thereof, so thatthe hinge will be extremely durable and resistant 'to strains such .asusually caused during final opening movement of either wing whenconsiderable momentum force is imparted to the hinge connection.

Other objects of the invention will be ap' parent from the followingdescription, the drawing relating thereto and the claims hereinafter setforth.

For a better understanding of the invention reference may be had to theaccompanying drawing forming a part of the specification, in whichFigure 1 is a fragmentary plan view of a vehicle-having a hoodconstruction designed according to on form of the invention;

Figure 2 is a cross-sectional view on a larger scale, takensubstantially along the line 22 of Figure 1,

Figure 4 is a cross-sectional view on a larger scale taken substantiallyalong the line 44 of Figure 2;

Figure 5 is a perspective, end view of the hood, particularlyillustrating the hinge connection between-the hood wings, as seen whdenthe hood is removed from the vehicle; an

Figure 6 is an end view on a larger scale, as seen substantially alongthe line 6-6 of Figure 5.

Referring to Figure-1, a motor vehicle is the veillustrated at 10, theradiator thereof at 11 wings are pivoted on a long pin or pintleconnected at opposite ends to the radiator and cowl, and the presentinvention particularly is concerned with the manner of hinging the wingstogether and to the radiator and cowl in an improved manner.

Referring now particularly to Figures 5 and 6, the hood wing 15 isillustrated as having an inwardly turned flange 17 and the wing 14similarly as having an inturned flange 18, such flanges being shown asspaced and substantially parallel when the wings are in closed position.The flange 17 is rigidly connected as by Welding, for example, to asimilar flange 20 on a male hinge element 21 formed by rolling an edgeof the element in the manner shown. The flange 18 on the hood wing 14similarly is connected to the flange 22 of a female hinge element 23adapted to cooperate with the male member 21. It of course should beunderstood that the dges of the wings 14 and 15 may be rolled to providethe male and female hinge elements respectively, without manufacturingsuch elements separately and then welding them to the wings, butordinarily the first described manner of manufacturing will facilitatethe metal rolling operations. The particular construction of the maleand female hing elements has been illustrated and described in mycopending applications for patent above identified, and accordingly, itdoes not seem necessary to explain them herein in detail. It may beadded that in many instances the male and female elements may constitutean article of manufacture, to be subsequently connected to hood wings bythe purchaser.

When the parts are associated as shown in Figure 6, it is apparent thatthe male and female members are so related that further closing movementof cit-her hood wing is resisted. In opening either wing, as for examplethe wing 15 as shown in broken lines, the hook portion of the male hingeelement, indicated at 24, finally hooks over the end edge of the femaleelement, indicated at 25, to provide a limit or stop to the openingmovement. Of course, if the wing 14 is opened, the male and femalemembers will move relatively in the same manner as when opening the wing15, although in the one case, the male element will move while thefemale element will remain stationary, while in the other case the maleelement will remain stationary and the female element will move. Themale and female elements are associated by longitudinally telescopingthem and it will be appreciated that the construction as shown simulatesthe ordinary hood hinge wherein a long pintle or pin is employed,without necessitating use of the latter. It is apparent that the maleand-female members are continuous from the cowl to the radiator andhence that water or other matter may not leak into the space below thehood through the hinge. The flanges 17 and 20 on the wing 15 and theflanges 18 and 22 on the wing 14, being positively connected together,will pre- 1 vent the ingress of any water or the like into the motorspace although, as stated previously, the male and female elements maybe integral with the wings so as to completely eliminate any possibilitof seepage of water or the like between the anges on either wing.

For pivoting the wings 011 the radiator and cowl, the male element 21extends beyond opposite ends of the hood as shown by Fig. 5, and suchpro ecting ends, as also illustrated in Figure 4, preferably constitutea portion of the male element, in which the flange 20 and a curved partof the element, are removed substantially to the line 25. While suchprojecting ends of the male member may not constitute an arcuate elementhaving a single radius of curvature, they may be satisfactorily pivotedin journals 27 mounted on the radiator and cowl. It would, of course, bepossible to have the projecting ends of the male element provided withtruly cylindrical surfaces so as to smoothly fit in the journals 27 butnormally this would not be necessary as satisfactory pivotal action maybe obtained without doing this, and it is much easier to use theprojecting ends of the male element without altering their curvature, asto make such alterations would introduce other manufacturing steps andincrease the expense of manufacture. The journals 27 have flanges 28 and29 fitting under portions 30 and 31 of the cowl and radiator and suchflanges are secured in position by means of bolts 32. Normally, the hoodwings 14 and 15 have their side edges resting on such portions 30 and 31of the radiator and cowl and this arrangement still further stabilizesthe position of the ends of the male element in the journals .27. v

In opening the hood wing 15, for example, it is apparent that the maleelement will move with the wing and hence pivot in the journals 27 andthat finally when the wing reaches its open position, the hook portion24 of the element will engage the end edge 25 of the female element tohold and lock the wing in open position. If the hood wing 14 is opened,the male element will remain substantially stationary and hence anysubstantial pivotal movement of its projecting ends in the journals 27will not be necessary. In a construction of this character, attention isdirected to the fact that a considerable manual and momentum force maybe exerted through a wing when it is thrown into its open position owingto the moment arm through which the force is imparted by the hand movingthe side edge of the wing and this force naturally tends to forcefullycontinue movement of the hood wing past its intended open position. Forexample, in opening the wing 15, there is a considerable force tendingto move the wing past its intended, open position in which the hook 24on the male element initially engages the end edge 25' on the femaleelement. In the ordinary hood in which a pintle is used, this force hasa very undesirable result in that eventually and ordinarily in a shorttime, parts of the hinge connection between the wings and between thewings and the cowl the radiator become broken. In the presentconstruction, after the wing 15 reaches the intended final openposition, the momentum force of the wing will be dissipated through thegive and resiliency of the hinge elements and largely through the femaleelement and adjacent .portions of the wing 14. If the wing 14 is opened,this force tending to move it past its final open position, isresiliently dissipated largely through themale element and the adjacentparts of the wing 15. Moreover, this momentum force does not actappreciably, if at all, on the journals 27 and the male element portionstherein except to rotate them, but to the contrary is dissipated mainlythrough the opposite wing and there is very little tendency to impartany force to the journals or the male elements therein to loosen thejournal connections on the radiator and cowl. This may be illustratedperhaps a little more clearly by using the arrow A in Figure 6. Inopening the wing 15, when the latter tends to move past its supposedlimited open position, the momentum force, instead of acting on thejournals 27, merely tends to slightly move the female element and partsof the wing 14, downwardly into the motor space in the directiongenerally indicated by such letter A. Of course, this movement is slightand practically unnoticeable, but nevertheless it is extremelyadvantageous in that it cushions the force and prevents the imparting ofundesirable forces to the journals 27, as well as to the rolled por-,tions of the hinge.

A hood of the type described may be manufactured very inexpensivelybecause it is only necessary to roll the male and female members fromedges of elongate and fiat plates and then fasten such elements to thewings,

' orelse roll such edges directly into edge portions of the wingswithout manufacturing them separately of the latter. The use of .pintlesor pins of any character is avoided and it is only necessary tomanufacture the wings and then pivot them on the radiator and cowl bymeans of projecting ends of the male element. The hinged constructionthus provided is water tight and, moreover, its appearance is especiallypleasing in that it simulates the ordinary type of hinge to which thepublic has become accustomed. Moreover, as stated in my prior copendingappli-.

cations for patent, the hinge is so constructed that surfaces exposed toview on the wings of the hood will not be marred or scratched during anymovement of the wings to their open or closed positions.

Although only one form of the invention has been described andillustrated in detail,
